[0002] PADDLE SHEET METAL SUPPORT SYSTEM IN REFERENCING SHEET METAL PIECE

[0003] TECHNICAL FIELD

[0004] This invention will be used in the field of sheet metal stamping by a die. It relates to preventing the sheet metal material to be formed from deviating from its position in the die under the effect of its own weight before stamping in forming or bending dies and consequently from being deformed incorrectly during forming.

[0005] STATE OF ART

[0006] In one of the existing systems, the sheet metal piece is positioned on a springmoving tongue with a width of 3.5 mm, given as the catalogue value. The force of the press pushes the holder tongue downwards together with the sheet metal piece. The retainer tongue is connected to a tension spring. After the operation, the retainer tongue returns to its initial position with the help of this spring. The support and referencing heights (I and 75mm) are limited. It appears to be structurally complex. Due to the space taken up by the retainer tongue and spring system in the set, the support and referencing height is limited (160mm-200mm). In long-term piece production processes, the efficiency of the tension spring life may decrease.

[0007] In another of the existing systems, the support and referencing heights are limited. The H height is given as a fixed 145 mm. The sheet metal piece is placed on the 40 mm wide movable tongue. The movable tongue rotates in the center of pin number 3. The center of gravity factor is taken as basis in the movement of the tongue. The reason why the tongue came to its place after the operation was because the back part was heavier compared to the center of gravity. In order to provide the conditions of the movement principle, the elements that make up the whole needed to be large in size. This situation, reflected in the overall dimensions, may create a disadvantage in terms of layout in designs.

[0008] In the patent document numbered CN201470770U, the process of crushing a cylindrical transmission part fixed on a shaft (6) by rotating it at 5 points at equal intervals is described. It is a patent developed in 2010. Here, the equal-range rotation process is provided by an impeller connected to the shaft end and has 5 threads. A pneumatic system compatible with manual intervention or press movement is required to ensure the rotation of the impeller.

[0009] In the patent document numbered CN201419205Y, a ratchet gear system was used to clamp a work piece rigidly. For the connection process, a gear impeller is used whose rotational movement depends on the angles and is predetermined and designed. The rotation of the impeller is done manually with the help of an arm. Additional complex structures were required for the centering of the rotation axis of the impeller and the fixing of the impeller.

[0010] DEFINITION OF THE INVENTION

[0011] The said invention eliminates the disadvantages described in the state of the art and meets the needs.

[0012] The said invention will be used in the field of sheet metal stamping by a die. In forming or bending dies, it relates to preventing the sheet metal material to be formed from deviating from its position in the die under the effect of its own weight before stamping and, as a result, from being deformed incorrectly during forming.

[0013] In the present patent applications, manual intervention or separate hydraulic- pneumatic systems were required to rotate the impeller systems. In our invention, when the process starts with the press compression, the rotary impeller makes the rotation movement with the guidance of the sheet metal material being processed and becomes ready as the position for the next process. The movement of the rotary impeller is provided by the currently moving press driving the rotary impeller to form the sheet metal without the need for an additional drive element.

[0014] The centering, positioning and impeller elements designed in the present patent applications are comprehensive and costly, and at the same time, disadvantageous in terms of space saving when considered within the die system. The elements used in our invention are smaller in size and less costly to produce or supply.

[0015] In our invention, the support and referencing height is optional. During design, the height can be determined according to the need and prepared as a support set. It has a simple structure. Dimensional advantage can be provided in terms of placement in designs. The wider width of the impeller (10mm) makes a positive contribution to the support of our sheet metal piece from below. The sheet metal material is prevented from tipping over due to the effect of weight. There is no risk of deformation of the edges of the sheet metal material before and during the process. It is possible for the impeller to turn backwards when removing the formed products from the dies. For this reason, jamming is prevented and the risk of deformation in the sheet metal material is reduced.

[0040] DESCRIPTION OF THE INVENTION

[0041] Elements used to define, but not limit, the said invention;

[0042] This invention is a paddle sheet metal support system in referencing sheet metal piece (5), comprising:

[0043] • sheet metal support body (1 ), which is the main body element carrying the system, where the impeller (2) is mounted,

[0044] • impeller center (7) located on the sheet metal support body (1 ), to which the impeller (2) is mounted via connecting piece (3),

[0045] • impeller mounting center (10) where the impeller (2) is mounted via the connecting piece (3) to the sheet metal support body (1 ) and which is located in the center of the impeller (2) and serves as the center of rotation movement, • impeller (2) on which the sheet metal piece (5) to be referenced can be placed and which makes referencing from the bottom and side,

[0046] - impeller tooth (2-a) which is the element where the surfaces (height reference surface (2-b)) are located for referencing the sheet metal piece (5) and which is distributed equally on the impeller (2),

[0047] - height reference surface (2-b), which is one of the surfaces forming the impeller tooth (2-a) and to which the sheet metal piece (5) is referenced as height from the bottom,

[0048] In the said invention, there may be a peripheral referencing surface (2-c) which provides the peripheral referencing of the sheet metal piece (5) and is one of the surfaces forming the impeller tooth (2-a), the peripheral referencing surface (2-c) only ensures the alignment of the sheet metal piece (5) in the horizontal plane. There may be other features that will ensure alignment of the sheet metal piece (5) within the die; with a design change (for example; by designing the peripheral referencing surface (2-c) as a curved surface instead of a flat one), the feature provided by the peripheral referencing surface (2-c) is eliminated, but the basic function of the invention, which is to support the sheet metal piece (5) from below, can continue to be provided. Therefore, the peripheral referencing surface (2-c) feature is not mandatory. However, when the peripheral referencing surface (2-c) is used, it can be used as surfaces perpendicular to each other (height reference surface (2-b), peripheral referencing surface (2-c)) for referencing the sheet metal piece (5).

[0049] In the said invention, there may be a connecting piece (3) that connects the impeller (2) to the sheet metal support body (1 ) and acts as a centralizing piece in the rotation of the impeller (2) around its own axis. The connecting piece (3) may be a retainer bolt. The said invention may include an impeller stopper (4), which is the part responsible for limiting the rotation ranges of the impeller (2). The impeller stopper (4) is mounted on the sheet metal support body (1 ) in the system.

[0050] In the said invention, the height of the sheet metal support height (6) is the height of the sheet metal support body (1 ) determined according to the need. It is optional.

[0051] The impeller center (7) located in the sheet metal support body (1 ) and the impeller mounting center (10) located in the impeller (2) can be in the form of a hole or a pin. Any of these two elements (impeller center (7), impeller mounting center (10)) can be a pin instead of a hole, so that the element with a hole on it can be mounted on this pin without the need for a retainer bolt (connecting piece (3)). The pin can be located in the sheet metal support body (1 ) or in the impeller (2). The element does not have to be in the form of a hole. It should not be limited in this direction.

[0052] In the said invention, the impeller center height (8) is the height at which the impeller (2) is mounted to the sheet metal support body (1 ), determined according to need. It is optional.

[0053] In the said invention, there may be an impeller stopper mounting hole (9), which is the hole where the impeller stopper (4) is mounted to the sheet metal support body (1 ).

[0054] In the said invention, there may be equally distributed impeller rotation holes (11 ) on the impeller (2) which are responsible for ensuring that the impeller (2) remains immobile until the next movement by corresponding to the impeller stopper (4) in each rotation movement. Preferably, there are 8 pieces.

[0055] The invention can be used in one or more pieces in forming and bending by a die. It is included in the system as a set. According to the position and location to be referenced, our invention is placed on the edge lines of the sheet metal piece (5) to be formed. The goal is to ensure that the sheet metal piece (5) remains in the correct position until the beginning of forming and that the sheet metal piece (5) is not damaged during forming.

[0056] Before forming, the sheet metal piece (5) is placed on the tooth-shaped step (impeller tooth (2-a)) on the support impeller (2). The edge of the sheet metal piece (5) supports on the vertical step peripheral referencing surface (2-c) from the side. The height reference surface (2-b), which is the horizontal step surface, prevents free fall by supporting the sheet metal piece (5) from below.

[0057] At the beginning of the forming, the sheet metal piece (5) is pushed downwards by the press machine to form it. As a result of the force coming from above, the sheet metal piece (5) is released from the impeller tooth (2-a) without deformation. The incoming force also ensures the rotation of the impeller (2), thus making the impeller (2) position ready for the next referencing.

[0058] The height of the sheet metal support body (6) and the height at which the impeller (2) will be mounted to the sheet metal support body (1 ) (impeller center height (8)) are optional values in mm, and are determined according to need in die designs. The impeller (2) is assembled using the connecting piece (3) (impeller retainer bolt etc.) by aligning the impeller mounting hole (10), which is the hole in the center of the impeller (2), with the impeller center hole (7) in the sheet metal support body (1 ). The impeller stopper (4) is mounted on the impeller stopper mounting hole (9) on the sheet metal body (1 ). In our invention, the ‘Ball spring pusher’ is used (preferred) as the impeller stopper (4). There are impeller rotation holes (11 ) at equal intervals on the impeller (2) for the stopper (4) to function. These impeller rotation holes (11 ) on the impeller (2) provide equal rotation movement of the impeller (2) in each reference. The impeller rotation holes (11 ) on the impeller (2) are attached to the impeller stopper (4) in each rotation movement and an equal amount of rotation movement is provided.
